Zero in on your zero-day vulnerabilities
A zero-day attack comes, by definition, out of the blue. You cannot predict its nature or assess how much damage it might cause, but you can take some basic steps to protect yourself from a potentially crippling cyber strike
Zero-day exploits do exactly what they say on the tin: they take advantage of a previously unknown vulnerability in software, so it is the attack itself that alerts the world to the security flaw. No advance warning, no fixes immediately available.
While such attacks are relatively rare and their duration tends to be short as suppliers rush to release a patch, their impact can be huge. Some zero days may expose you to zero risk, but others could allow remote access to your most sensitive data...
